Passive transponder
Abstract
Abstract Translated from French Les éléments d'antenne (1,2) du transpondeur sont percés d'ouvertures (6,7) et ont donc la forme générale de boucles entourant des espaces dépourvus de tout élément métallique. Cette constitution diminue la capacité du condensateur parasite formé par les éléments d'antenne (1,2) et le corps de la personne qui porte le transpondeur, ce qui améliore le rendement de ce dernier. Application notamment à la recherche de personnes victimes d'avalanches. The antenna elements (1,2) of the transponder are pierced with openings (6,7) and therefore have the general form of loops surrounding spaces devoid of any metallic element. This constitution reduces the capacity of the parasitic capacitor formed by the antenna elements (1,2) and the body of the person carrying the transponder, which improves the efficiency of the latter. Application in particular to the search for people victims of avalanches.
